Detailed Description
The purpose of this study is to assess the efficacy, safety, and pharmacokinetics of eravacycline compared to ertapenem in treating participants with complicated urinary tract infections (cUTI).
This is a phase 3, randomized, double-blind, double-dummy, multicenter, prospective study to assess the efficacy, safety and pharmacokinetics of eravacycline compared with ertapenem in the treatment of cUTI.
Randomization will be stratified based on two criteria: (1) by primary site of infection (pyelonephritis and normal urinary tract anatomy vs all other diagnoses) and (2) by the receipt of a single dose of effective non-study antibiotics for the acute cUTI within 72 hours prior to randomization. An enrollment cap of approximately 50% is planned for subjects with pyelonephritis with normal urinary tract anatomy. Also, an enrollment cap of approximately 20% is planned for subjects who have received a single dose of non-study antibiotics for the acute cUTI within 72 hours prior to randomization.
In this study subjects will be enrolled and randomized to one of two treatment arms in a 1:1 ratio: (i) eravacycline intravenously (IV) / levofloxacin (PO), or (ii) ertapenem (IV) / levofloxacin (PO).

Description
Inclusion Criteria:
Male or female participant with either:
- Pyelonephritis and normal urinary tract anatomy (approximately 50% of the total population), or
cUTI with at least one of the following conditions associated with a risk for developing cUTI:
- Indwelling urinary catheter
- Urinary retention (at least approximately 100 milliliters (mL) of residual urine after voiding)
- History of neurogenic bladder
- Partial obstructive uropathy (for example, nephrolithiasis, bladder stones, and ureteral strictures)
- Azotemia of renal origin (not congestive heart failure [CHF] or volume related) such that the serum blood urea nitrogen [BUN] is elevated (>20 milligrams [mg]/deciliters [dL]) and the serum BUN:creatinine ratio is <15
- Surgically modified or abnormal urinary tract anatomy (for example, bladder diverticula, redundant urine collection system) except urinary tract surgery within the last 30 days (placing of stents or catheters is not considered to be surgical modification)
- At least 18 years of age at time of consent
- Able to provide informed consent
At least two of the following signs or symptoms:
- Chills, rigors, or warmth associated with fever or hypothermia
- Flank pain (pyelonephritis) or pelvic pain (cUTI)
- Nausea or vomiting
- Dysuria, urinary frequency, or urinary urgency
- Costo-vertebral angle tenderness on physical examination
Urine specimen with evidence of pyuria
- Dipstick analysis positive for leukocyte esterase (where positive result is at least "++" as indicated on the urine dipstick provided in the laboratory kit), or
- ≥10 white blood cells (WBCs) per cubic millimeter, or
- ≥10 WBCs per high power field

- If female, not pregnant or nursing or, if of childbearing potential: must commit to either use at least two medically accepted, effective methods of birth control (for example, condom, spermicidal gel, oral contraceptive, indwelling intrauterine device, hormonal implant /patch, injections, approved cervical ring) during study drug dosing and for 14 days following last study drug dose or practicing sexual abstinence

- Unlikely to survive at least through the duration of the study
- Hypotension, systolic blood pressure ≤90 millimeters of mercury [mmHg]

- History of renal transplantation
- Presence of an ileal loop
- Any history of trauma to the pelvis or urinary tract occurring within 30 days of screening

- Neutropenia (Absolute neutrophil count <1,000 polymorphonuclear leukocytes [PMNs]/microliters [µL])
- Participation in a study with an experimental drug or device within 30 days prior to enrollment
- Known or suspected hypersensitivity to tetracyclines, carbapenems, or β-lactams
- History of seizures

Measure Description |
Time Frame |
---|---|---|
Proportion of Participants in the Micro-ITT Population Demonstrating Clinical Cure and Microbiologic Success at the EOI Visit
Time Frame: End of Infusion
|
This was the co-primary outcome measure for the Food and Drug Administration (FDA).
The primary objective was to demonstrate the non-inferiority (NI) of eravacycline to ertapenem in responder outcome, which was derived from both clinical and microbiological responses, in the micro-ITT population.
Clinical responses were either cure, failure, or indeterminate/missing; microbiological responses were characterized programmatically as either success, failure, or indeterminate/missing.
Clinical cure was defined as complete resolution or significant improvement of signs or symptoms of the infection; microbiological success was a reduction of the baseline pathogen(s) to <10^4 colony-forming units/milliliter (CFU/mL).
An outcome of Responder required a clinical response of cure and a microbiological response of success.
Any other combination of the clinical and microbiological responses was considered either Non-responder or Indeterminate.

Proportion of Participants in the Micro-ITT Population Demonstrating Clinical Cure and Microbiologic Success at the Test-Of-Cure (TOC) Visit
